3 Easy Steps to Finding Your Bra Size
Not sure about your size? All good, we don’t blame you! Sizing varies by brand which is why we did our best to make finding your perfect bikini as easy as possible.
Before we start you will need a few things: A soft measuring tape, a mirror and your best fitting, least padded bra (no sport bras).
*If you are like most households and don't have a soft tape measure, use a string and hold it up to a ruler
step 1
measure your bust
Measuring your bust to get your cup size:
Slide your measuring tape up your back, across your shoulder blades and across the fullest part of your bust (over your nipples or see letter A).
Keeping the measuring tape straight across your back, hold the tape as loosely as possible (without it drooping too much) and take note of that measurement.


step 2
measure your band
Wearing your best fitting bra and wrap the measuring tape straight around your back just under your bust (see photo).
Measure tight against your rib cage and note measurement.
*if using a string, take the part wrapped around you and
hold that against a measuring tape/ruler to see how many inches it is
Calculating: If your measurement is an odd number, add 1, if it's an even number, add 2.
Ex: 35 inches rounds up to 36
Ex: 32 inches rounds up to 34
step 3
calculate your cup
Let’s do a little math!
Your band measurement is what you measured + 1 (odd measurements) or 2 (even measurements)
For every inch difference between your band size and your bust size you will increase your cup size.
Ex: 34 inch band and a 39 inch bust (5 inch difference) will be a 34DD
Ex: 31 inch band measurement will round up to a 32 and a 35 inch bust (3 inch difference) will get you to size 32C.
